The New Zealand Land Cover Database (LCDB) is digital map of the land surface of the country. It is created by grouping together similar classes which can be identified in satellite images. Being digital, it can be used to make a number of different maps. As a map, it can be combined with other geographic information to reveal new information on patterns and trends of land use and land cover. The Land Cover Database version 2 contains snapshots of land cover at 1996-97 and 2001-02 incorporated into the data layer.
